Abstract

Heat seal coated biaxially oriented synthetic linear polyester film is produced by melt extruding a substantially amorphous polyester film drawing the film in the longitudinal direction, thereafter applying a heat seal coating to one or both sides of the film and then drawing the coated film in the transverse direction. The synthetic linear polyester may be polyethylene terephthalate. The film may be drawn in the longitudinal and transverse directions at a temperature between 78 DEG and 125 DEG C, e.g. longitudinally at 78 to 100 DEG C and transversely at 80 to 125 DEG C. Examples of polymers which may be present in the heat seal coating are given. The film may be drawn longitudinally by passing it between or around a pair or a series of slow rollers which may be heated to the desired temperature and then between or around a pair or a series of fast rollers. The film may be heated by means of radiant heat applied to a small length of film between the fast and slow rollers. The biaxially oriented coated film may be subsequently heat set at 150 to 230 DEG C. The heat seal coating may be applied as a melt, a solution in an organic solvent or an aqueous dispersion.
